DIGITAL THERMOGRAPHIC METHODS, SYSTEMS, AND PRODUCTS
A method for producing a printed product with raised print includes receiving a prepress format document containing a plurality of flat ink color separations and at least one raised print color separation, printing onto a substrate the flat ink color separations using flat ink and the at least one raised print color separation using dimensional ink, allowing the flat and dimensional ink to dry, heating the inked substrate to a temperature that causes the applied dimensional ink to become sticky, applying thermographic powder to the heated inked substrate such that the thermographic powder sticks to the sticky dimensional ink, removing the thermographic powder from regions of the substrate where the dimensional ink is not applied, reheating the sheet to melt the thermographic powder, and cooling the sheet to result in a print product having both flat and raised printed content.
1 . A raised print product comprising:
a substrate having regions of raised print;
a dimensional ink layered on top of the substrate and a thermographic material layer on top of the dimensional ink layer in the regions of raised print.
2 . The raised print product of claim 1 , wherein the substrate includes regions of flat print.
3 . A system for producing a printed product with raised print, comprising:
a dimensional ink printer which receives a print-ready document containing CMYK and dimensional ink color separations and prints the print-ready document onto a substrate using flat ink for the CMYK colors and dimensional ink for the dimensional ink separation;
a first heating unit which receives a dry printed substrate printed by the dimensional ink printer and heats the dry printed substrate to cause the dimensional ink to become sticky;
a thermographic powder dispenser which applies thermographic powder to the heated dry printed substrate such that thermographic powder sticks to the sticky dimensional ink;
a thermographic removal apparatus which removes thermographic powder from regions of the heated dry substrate where dimensional ink is not applied; and
a second heating unit which melts the thermographic powder applied to the dimensional ink.
4 . The system of claim 3 , wherein the dimensional ink printer is a digital printer.
5 . The system of claim 3 , wherein the first heating unit and the second heating unit is the same heating unit.
6 . The system of claim 3 , further comprising:
a cooling unit which cools the melted thermographic powder.
